Marine Rubber Airbags
General
This Marine rubber airbags can be used for ship launching/landing, marine salvage, and heavy lifting. All marine rubber airbags are made by innovative holistic wrapping technology. Manufactured and tested comply with ISO 14409 standard.
This Marine rubber airbag used as ship launching airbag is a innovative ship launching technology. This technology has been accepted by more and more ship owners and shipyards, nowadays. Ship launching airbags are used by more shipyard world wide because of its advantages of saving time and investment, flexible, safety.
Construction Features
This marine airbags are to be constructed of out-rubber layer, multilayer high heavy-duty synthetic-tire-cord layers, and inner rubber layer vulcanized firmly. Marine air bags are cylindrical rubber body, with two conical heads and metal end fittings at the heads covered with end-mouth.
Materials & Specifications
-
Synthetic-tire-cord Layer: Nonreinforcement layer of marine air bags which are made of rubber-coated nylon fabric. The texture is manufactured by using the newly developed and patented “Holistic Wrapping Technology”. To hold the internal pressure and to distribute the stresses equally, We use the 2000d-2/1 type synthetic-tire-cord fabric. The warp is over 85 cords per 100mm in width, and the breaking strength is more than 215N/per cord.
